Description

[Detailed description of the invention] name of invention golf tee The invention relates to a golf tee of the type specified by the preamble of claim 1. of this type, already known and described in GB-C-236 132, In a golf tee, each of the plurality of vertical members is tapered toward its free end. They are provided like elastic fingers or like bristles.

There is an unavoidable problem with the insertion of this known golf tee into the ground. Ru. That is, the insertion part cannot be completely inserted into the earth's surface. shown in the quote In one embodiment, a slightly enlarged portion at the top of the insert always remains above the surface. Bullet The sex toes or bristles should be as small as possible for a golf club swung very low. Resistance is provided as elastically as possible so that its elastic fingers or rigid Hair cannot be used to push into the earth's surface. Their elasticity is The ball should be adjusted so that it has just the right support to ensure it is placed on the tee. It is.

However, the insertion section allows the tee to be pushed into the ground. Must be made of hard material. In the case of known golf tees, When a golf club is swung very low, the ≠ Not only the ball support part of the ball but also the insertion part cannot be prevented from being hit. this is It's inconvenient.

The object of the invention is to enable the insert to be pushed completely below the surface of the earth, and at the same time In order to simplify the process of inserting a golf tee into the ground, GB-C-236 132, by improving the already known golf tee of the above type. be.

This object is specified in the feature clause in claim 1 based on the above-mentioned features. This is achieved through the features provided.

This golf tee uses an insert made of material with high compressive strength. By law, the insert must be inserted at least far enough into the ground so that its upper end remains above the ground. In addition, it is possible to insert the upper end slightly into the ground. It is Noh. This ensures that the insert will not be struck even if the golf club is swung very low. You can prevent this from happening. Moreover, the longitudinal members are each A predetermined length above the attachment point of the vertical member is struck, and in that part, the longitudinal member is , it has high flexibility from the beginning. The head of the golf club should not be deflected; 's trajectory is completely unimpeded. This occurs when the golf club is swung very low. , the golf tee being knocked off the ground, and damage to the golf tee, or will definitely prevent destruction. Damage to the golf club head is also prevented. addition Thus, the insert can be relatively small and inexpensively formed. The insertion part is a place to grasp with your hand. It is not necessary to have . The insert will never wear out and will last a long time. It can be used for the golf tee of the present invention.

Insertion of a golf tee into the ground is radically simplified by this insertion tool.

In a more preferred design, the insert has a recess centrally inside its ring portion. Ru. The surface portion of the recess forms the receiving surface. The lower end of the insert should fit into the recess. It is shaped like a sea urchin. This simplifies the connection between the insertion part and the insertion tool. another improvement In this case, the insertion part has a ring-shaped protrusion on the outside of its ring part. The surface of the protrusion The surface part forms a receiving surface. The inserter receives a ring-shaped lower end and a longitudinal member. It has a space for In the latter case, the insertion tool will Grip it on the outside. In one embodiment of the invention already mentioned, the golf tee insert and the insertion device are provided such that the releasable connection is made only in the direction of insertion. Therefore, place the insertion tool firmly on the insertion site so that it cannot move laterally relative to the insertion site. It fits perfectly.

In another more preferred embodiment of the invention, the insert is longer than the longitudinal member. this In the method, the longitudinal member is not compressed or deformed when an insertion force is applied.

In a particularly preferred design, the insert and the ball support are formed by a plastic body. ing. This golf tee can be manufactured very cheaply by injection molding. .

Moreover, when inserting the insert into the natural ground surface, the insert can be shaped conically. effective, whereas artificial substrates for golf practice, such as rubber mats, A cylindrical shape is preferable when inserting into a In each case, the insertion site Ensures that the lufty is firmly held to the substrate. Natural surfaces such as lawns In this case, the supporting surface is conical. In the case of artificial substrates such as rubber mats, a cylindrical A concave part is provided in the artificial base, and a similar cylindrical shape is placed in the cylindrical 1M1 part. The inserted part that has been made can be pushed in.

Finally, the insertion part and the insertion tool are secured to each other, e.g. by screws or bayonet pins. It would be convenient if it were possible. This connection allows the insert to place the golf tee on the ground. Of course, it can also be used to extract

Generally, it is considered suitable to arrange the vertical members on the sides of the cone. Vertical section It is better for the material to have an essentially constant cross-sectional area along its length. Cross section of longitudinal member The diameter is at least one-twentieth of its total length.

Additional features and inventive step of the present invention will be apparent from the separate claims. The above will be discussed in the embodiments of the invention below. This example is an example of the present invention. Of course, this does not limit the present invention. These examples are: It is explained in detail in the figure.

FIG. 1 is a perspective view of a golf tee to which the present invention is applied.

FIG. 2 is a perspective view similar to FIG. 1 of a slim golf tee.

FIG. 3 is a cross-sectional view of the golf tee and insert.

FIG. 4 shows another shaft of a golf tee with a cylindrical insert inserted into a mat. be.

Each of the golf tees shown in the figure has a ball support part 20. The holding portion 20 has a plurality of pieces arranged in a crown shape, each having basically the same length and having flexibility. It is formed by a vertical member 22 having. The upper free end of the longitudinal member is It forms a support surface 24 for the golf ball. In addition, each golf tee , having an insert 26 which inserts the longitudinal member 22 into the substrate 30.32. , and a support surface 34 for mounting on the substrate 30.32, and a book on said ring portion 36. It can be inserted in the insertion direction that should be qualitatively followed. At the ring portion 36, the lower end of the vertical member 22 is coupled to the insertion portion 26.

The longitudinal member 22 has a length of 20 mm to 50 mm. The vertical member 22 is It essentially has a constant cross-sectional area. The dimensions of the cross section are typically for a rectangular cross section. I×1 square mm, and in a circular cross section, the diameter is 1 mm. The vertical members 22 each have a The golf ball has been selected to be more supportable. The vertical member 22 is shown in the figure. It can be bent freely from each position shown.

The insert 26 has a receiving surface 38 for the insert 40 . The receiving surface 38 is vertical It lies transversely with respect to the orientation of member 22. The insertion tool 40 has a receiving surface 3 at its lower end. It has a support surface 42 that fits 8. Then, the insertion tool 40 is inserted into the upper end thereof. It has a pushing surface 44 for applying input.

In one embodiment shown in FIG. 4, the receiver surface 38 is located inside the ring portion 36. Ru. A pocket drill hole 46 is provided in the insertion portion 26 from the surface on which the support surface 42 is provided. It is placed facing downward. The lower end of the insertion tool 40 has a corresponding outer shape. It is formed. The insert 40 can fit snugly within the pocket drill hole 46. It has a downwardly extending portion. This guides the insertion of the insertion tool 40 into the insertion section 26. , to prevent the insertion tool 40 from wobbling.

Thereby, the force exerted by the insertion tool 40 in the insertion direction is transmitted to the insertion section 26. I can do it.

In the design of FIG. 1, the receiver surface 38 is located on the outside of the ring portion 36, and the receiver surface 38 is located on the outside of the ring portion 36. 8 at its outwardly projecting edge 48 facing in the direction of the longitudinal member 22. formed by the upper surface of the ring surface. In this case, the inserter 40 is inserted as shown in FIG. It is not fundamentally shaped like a bottle, but has a tube-like shape. of this tube The inner diameter is selected so that the longitudinal member 22 can be inserted into the tube and The end face of the tab rests on the edge 48, i.e. on its receiving surface 38.

In one embodiment shown in FIG. 4, an insert 40 formed similarly to the insert of FIG. It has a threaded end. This engages with the matching internal thread 50 of the insertion section 26. , the upwardly facing threaded surface of this internal thread 50 forms a bearing surface 38 . This screw If the insertion tool 40 and the insertion portion 26 are connected to each other in a manner that resists compression and tension, Therefore, this device can be used for both golf tee insertion and golf tee withdrawal. I can be there.

The golf tee in Figure 1 is made of injection molded plastic polyamide (nylon). It is made as a single unit of (known as). A golf tee has a conical shape. In particular, the insertion part 26 has a conical shape.

The angle of the cone is 18 degrees. The insertion portion 26 has a length of approximately 16 mm. There is. A total of 16 vertical members 22 are provided along the side surfaces of the cone, and approximately 22 vertical members 22 are provided along the sides of the cone. It has a length of millimeters. By providing a large number of longitudinal members 22, each longitudinal member 22 can be formed relatively soft. A golf ball is supported by all vertical members. available. When the golf club head hits the vertical member 22 from any direction, the vertical member 2 2 turns sideways with virtually no resistance, so the golfer can I swing so low that I hardly feel anything when I hit the golf tee. What should be said regarding this elasticity is that the insertion portion 26 is attached to the surface of the substrate 30. Since the ring portion 36 is located deep below the surface of the That's what it means. In this way, a trajectory that is too low will always cause the longitudinal member 22 to Pressure is applied only to the root trunk, that is, to the part that can be elastic.

Figure 2 shows a particularly skinny golf tee, which is suitable for Samurai on hard surfaces. ing. The longitudinal members 22 are curved outwardly to form a flared ball support surface. I'm looking forward to it. The receiving face 38 (not shown) for the nail-like insert is located inwardly. It is location.

In one embodiment shown in FIG. 3, the free end of the longitudinal member 22 is provided with an outwardly directed thickening 54. It is growing. They enlarge the upper end surface and form a support surface 24. Therefore , they support the hand that pulls the tee out of the ground. facilitates removal.

In the case of the insert 40 shown in FIG. It is formed so that it can be placed on the pushing surface 44 of. Therefore, the insertion force can be applied directly by hand. There is no need to move, and the golf ball is placed between the golf tees. Inserting into the table becomes easier.

Unlike the embodiment shown in the other figures, the insert 26 in the embodiment shown in FIG. 4 is cylindrical. Ru. The insertion part 26 inserts a pocket drill into the mat forming the substrate 32. inserted into the hole. The insertion tool 40 used for this purpose has an insertion section that is susceptible to friction. It is possible to apply sufficient force to the cylindrical insertion portion 26 so that it can be gripped firmly and firmly. Because the golf tee is It cannot be removed.

As shown in FIG. 3, the insert is longer than the longitudinal member 22; therefore, the longitudinal member is The insertion tool 40 shown in FIG. It is set in the name.

near the support surface 42 of the insertion tool 40 and/or near the receiving surface 38 of the insertion section 26. It has been found that it is effective to provide a guide surface 56, and the guide surface is , is basically provided along the insertion direction and has a length of several millimeters (approximately 4 mm). So shaped to guide you when placing the golf tee and insert together. Therefore, the surfaces 38, 42 are in positive contact with each other and this contact prevents lateral movement. impede movement. At least one guide surface 56 forms a conical frustum. It is preferable.
